mccarthy and we say your gun was used in a crime and that guy says it was stolen out of his house two years ago. was it? i think for purposes of keeping track of where our guns are the idea of mandatory reporting is a good idea. is 24 hours enough? that's up for debate. >> what about restricting the age of buying ammunition up to 21? >> i think that's fine. there could be other restrictions for ammunition or taxes, and we tax cigarettes and liquor at high levels and it might make sense to put high texass and discourage some of the sales. >> none of these are bad ideas. the question when it comes to ammunition, whether you raise it to 21 or ban internet sales of ammunition, and if one would say which of the two would i rather have, i would rather have the banned selling on the internet of ammunition, and we are facing a challenge on the other side, the more reasonable we are, i think, and precise in our goal setting the more likely we are to achieve something positive. >> john mccarthy, and glenn ivy, former prince georges' states attorney, thank you both for being here. thank you for
